multiple favorite channel groups

[xris]

I'm very close to just implementing this specifically for mythweb, but since I see it as a valid feature for mythfrontend, I'd like to work with whoever is in charge of this to come up with a solution that everyone can use...

My DishNetwork controller has the ability to create up to 4 channel groups, plus the default "all" group. I'd like something like this for mythtv, so I can segment off groups of channels I may not often want to watch or see in listings (say, all of the sports channels), but don't want to just ignore come time for the X-games, olympics, etc. Same goes with news channels, etc. It shouldn't be too hard to expand the current single-option favorites into a set of named favorite channel groups. As long as a standard is agreed upon, even if not implemented within the frontend for awhile, I can at implement it (and an editor for it) within mythweb, which is the only place I ever use the program guide.
